GHK (Copper-Free) 100mg Reconstitution: How Much Bacteriostatic Water & How Many Units
A 100mg vial of GHK (Copper-Free) contains 100,000 mcg. After you add bacteriostatic water, the amount of water decides the concentration — and therefore how many units you draw on a U-100 insulin syringe (1 ml = 100 units). The tables below cover the common water amounts.
Concentration by water amount
| Water added | Concentration | Per 1 unit (0.01 ml) | Per 10 units (0.1 ml) |
|---|---|---|---|
| 3 ml | 33.33 mg/ml | 333.33 mcg | 3.33 mg |
| 5 ml | 20 mg/ml | 200 mcg | 2 mg |
| 10 ml | 10 mg/ml | 100 mcg | 1 mg |
How many units to draw
Example doses across the research range listed for GHK (Copper-Free) (2 mg–5 mg). Units are on a U-100 insulin syringe.
| Dose | With 3 ml | With 5 ml | With 10 ml | Doses per vial |
|---|---|---|---|---|
| 2 mg | 6 units | 10 units | 20 units | 50 |
| 3 mg | 9 units | 15 units | 30 units | 33 |
| 4 mg | 12 units | 20 units | 40 units | 25 |
| 5 mg | 15 units | 25 units | 50 units | 20 |
How to mix it
- Wipe the vial stoppers with alcohol and let them dry.
- Draw your chosen amount of bacteriostatic water into a sterile syringe.
- Inject the water slowly down the inside wall of the GHK (Copper-Free) vial — not directly onto the powder.
- Swirl gently until clear. Do not shake.
- Label the vial with the date and concentration, and store it in the refrigerator.

FAQ
How much bacteriostatic water do I add to a 100mg GHK (Copper-Free) vial?
Common choices are 3 ml, 5 ml, 10 ml. With 5 ml the concentration is 20 mg/ml. More water makes each dose a larger, easier-to-measure draw; less water keeps injection volume small. The amount of water does not change the dose — only how many units you draw.
How many units is 2 mg of GHK (Copper-Free) from a 100mg vial?
With 5 ml of bacteriostatic water, 2 mg is 10 units on a U-100 (1 ml) insulin syringe. See the table above for other water amounts.
How many doses are in a 100mg GHK (Copper-Free) vial?
At 2 mg per dose, a 100mg vial holds about 50 doses. At higher doses it holds fewer — see the table.
